An apparatus and method for providing multimedia conferencing services over an ATM network with an unspecified bit rate quality of service class. Because the signals of the unspecified bit rate multimedia conference will be dropped before those of any guaranteed quality of service conferences, a multimedia bridge monitors the ATM network for congestion. If congestion is detected, the multimedia bridge searches for alternate non-congested paths so that the UBR multimedia conference can be maintained without cell losses. If no non-congested paths are found, the multimedia bridge scales the video portion of the UBR multimedia conference signals so that the UBR multimedia conference can continue. The scaling is performed in accordance with user-defined parameters that result in a reduced bandwidth video signal that can be transmitted along the congested ATM network.
A method for operating a multimedia bridge of a type that provides a multimedia conference among a plurality of user devices over a packet network, the method comprising:
